ci: handle first performance-gated main promotion

HACS will install from the named asset instead of the auto zipball, so
GitHub's public download counter becomes a per-version install metric.
The workflow also has a manual dispatch to backfill an existing release.

 The startup update script already runs `npm ci`, provisions a Python 3.13 backend venv at `.venv-backend`, and installs Playwright Chromium. You do not need to reinstall dependencies.
 
-- **Frontend** (from repo root): `npm run typecheck`, `npm test` (node:test, ~270 tests), `npm run build`. After building, keep the integration copy in sync — `cp dist/houseplan-card.js custom_components/houseplan/frontend/`. CI enforces `cmp dist/houseplan-card.js custom_components/houseplan/frontend/houseplan-card.js` byte-for-byte.
-- **Backend HA-harness tests need Python 3.13, not the system 3.12.** Run them with the venv: `.venv-backend/bin/python -m pytest tests_backend/ -q` (126 tests). Running `python3 -m pytest tests_backend` on the system 3.12 silently **skips** the `test_ha_*.py` harness tests (`conftest.py` ignores them when `homeassistant` is not importable) and runs only the ~83 pure tests.
-- **Running the app / smoke suite**: build a fresh bundle and copy it into the demo assets first — `npm run build && cp dist/houseplan-card.js demo/srv/assets/houseplan-card.js` — then run `node demo/smoke_*.mjs`. The committed `demo/srv/assets/houseplan-card.js` is a stale snapshot; testing it reports green about code that no longer exists. No real Home Assistant server is required: `demo/srv/demo.html` stubs `hass`, registries and `callService`.
+- **Frontend** (from repo root): `npm run typecheck`, `npm test` (node:test, 424 tests at v1.60.0), `npm run build`. After building, keep both committed snapshots in sync — `cp dist/houseplan-card.js custom_components/houseplan/frontend/` and `cp dist/houseplan-card.js demo/srv/assets/`. CI enforces both comparisons byte-for-byte.
+- **Backend HA-harness tests need Python 3.13, not the system 3.12.** Run them with the venv: `.venv-backend/bin/python -m pytest tests_backend/ -q` (150 tests at v1.60.0: 100 pure + 50 HA harness). Running `python3 -m pytest tests_backend` without Home Assistant silently **skips** the `test_ha_*.py` harness tests (`conftest.py` ignores them when `homeassistant` is not importable) and runs only the pure set.
+- **Running the app / smoke suite**: build a fresh bundle and copy it into the demo assets first — `npm run build && cp dist/houseplan-card.js demo/srv/assets/houseplan-card.js` — then run `node demo/smoke_*.mjs`. The committed demo snapshot must remain byte-identical to `dist` (CI checks it); rebuilding first also guarantees the browser suite tests the current source in an uncommitted worktree. No real Home Assistant server is required: `demo/srv/demo.html` stubs `hass`, registries and `callService`.
+- **Golden images**: `npm run golden:capture` and `npm run golden:verify` refuse a stale demo bundle. Build and copy the current bundle first, then review `artifacts/golden/actual/` and `diff/`. Update baselines only with `npm run golden:accept -- --reviewed`, using the complete Linux CI artifact; never accept a partial scenario or images merely to make CI green. See `demo/golden/README.md`.
+- **Freshness contract**: the embedded fingerprint covers `src/` plus Rollup, TypeScript and package-lock build inputs. Benchmark and golden tooling must call `assertFreshDemoBundle` before recording any result; a missing or mismatched fingerprint is a hard failure, not a warning.
 - **Demo harness render quirk**: the fake `hass` in `demo.html` is set once, so opening the page directly in a browser renders the floor plan but **device icons only appear after a re-render** (an F5 refresh, or nudging `card.hass = {...card.hass}`). The smoke launcher `demo/serve.mjs` already does this nudge; a plain browser session does not. This is a harness limitation, not a card bug.
 - **Known environment-sensitive smoke**: `demo/smoke_opening_measure.mjs` fails two sub-checks (`place_dialog_x_magnetised`, `place_committed_x_center`) under the pinned Chromium — a `1e-6`-tolerance magnet-snap on the opening-*placement* path. It reproduces against the pristine committed bundle, so treat it as pre-existing/pixel-precision, not a regression you introduced.

+# HP-QA-01 golden images
+
+This layer catches visual regressions that DOM smokes cannot: wall seams and
+end caps, thick opening tunnels, Glow/sun clipping, hover contours, editor
+chrome, the open contextual tray at wide/medium/narrow widths in English and
+Russian (selection, tool options, group and palette), long dialog
+titles/footers, mobile clipping, themes and zoom/remount.
+
+## Safety contract
+
+- A build fingerprint embedded by Rollup must match `src/`, Rollup/TypeScript
+  configuration and locked package inputs; stale committed
+  demo bundles fail before the first screenshot.
+- Chromium, viewport, locale, timezone, colour profile, font rendering,
+  animations and caret are controlled by the runner.
+- `capture` writes only to ignored `artifacts/golden/`; it never changes a
+  baseline and never claims a missing baseline passed. Any scenario runtime
+  error makes capture fail, including the initial no-baseline CI run.
+- `verify` requires every image plus a matching matrix manifest and fails on
+  missing/different/error scenarios, browser mismatch or a baseline whose hash
+  no longer matches the reviewed manifest.
+- `accept` requires `--reviewed`, a complete candidate report and current
+  source fingerprint. It validates the whole set before copying anything and
+  is the only command allowed to update baselines.
+
+## Workflow
+
+Build and copy the exact current source first:
+
+```bash
+npm run build
+cp dist/houseplan-card.js demo/srv/assets/houseplan-card.js
+npm run golden:capture
+```
+
+Review `artifacts/golden/actual/` and, when existing references are present,
+`artifacts/golden/diff/`. If every image is intentional:
+
+```bash
+npm run golden:accept -- --reviewed
+npm run golden:verify
+```
+
+Never accept images merely to make CI green. A matrix/framing change increments
+`GOLDEN_MATRIX_VERSION`; a normal rendering fix does not. The first canonical
+Linux baseline was reviewed and accepted during the v1.60.3-beta.1 gate.
+Future updates must still use the `golden-images` artifact produced by the Linux
+CI job as the review set: desktop font rasterisation can differ from the CI
+environment even with the same pinned Chromium. Pass its unpacked root via
+`--from=...` when accepting it locally.

+# Large-house performance gate
+
+`benchmark_large_house.mjs` exercises the deterministic `large-house-v1`
+fixture. The fixture has 60 rooms, 200 devices, 100 openings, 60 partitions,
+40 columns and 500 decor objects on three floors.
+
+The runner records seven measured samples after one discarded warm-up. With
+this intentionally small CI sample, the nearest-rank `p95` is the observed
+maximum; reports keep the conventional field name but should be read as a
+high-tail guard rather than a population estimate:
+
+- model readiness and first stable render;
+- space switch, HA state update, pan/zoom and opening the settings dialog;
+- a shared-wall room-resize preview which is cancelled before persistence;
+- a twelve-switch navigation cycle;
+- Long Tasks for every measured window;
+- heap growth after four additional navigation rounds with forced GC;
+- hot-cache size and growth after the same warmed cycles.
+
+Every report is tied to the source fingerprint embedded by Rollup. A stale
+bundle is a hard failure.
+
+## CI contract
+
+The `performance` job checks out the candidate and its base SHA, builds both,
+and runs them sequentially with the same Node.js 22 process family, pinned
+Playwright Chromium and hosted runner. `compare.mjs` then applies two limits:
+
+1. a relative regression allowance against the base-SHA report;
+2. an absolute safety ceiling from `budgets.json`.
+
+The tighter limit wins. The absolute values are catastrophic safety ceilings,
+not normal-performance targets; the base-relative comparison catches smaller
+regressions. Small fast operations receive an absolute noise
+allowance so normal scheduler jitter does not become a false regression. Heap,
+Long Tasks, warmed-cache growth and the expected rendered-device count are
+gated separately. Long-Task maximum/count/total checks use the same
+relative-plus-absolute policy as timings. Both raw reports and the comparison are always uploaded as
+the `large-house-performance` artifact, and the table is written to the GitHub
+job summary.
+
+This base-vs-candidate design intentionally does not compare timings captured
+on different machines or different Chromium builds. A runtime/profile mismatch
+fails closed.
+
+## Local diagnostics
+
+Build and copy a fresh demo bundle first, then run:
+
+```bash
+npm run benchmark:large-house -- --samples=7 --warmups=1 --output=artifacts/performance/local.json
+```
+
+A local report is diagnostic only; it cannot replace the CI comparison.
+
+To reproduce the comparison against another checkout using one harness and one
+browser installation:
+
+```bash
+npm run benchmark:large-house -- --target-root=../base --samples=7 --output=artifacts/performance/baseline.json
+npm run benchmark:large-house -- --target-root=. --samples=7 --output=artifacts/performance/candidate.json
+npm run benchmark:compare
+```
+
+## Changing budgets
+
+Budget changes require an explicit review of recent CI artifacts and a written
+rationale in the change. Do not loosen a threshold merely to make a single red
+run pass. A new fixture profile gets a new profile id instead of silently
+changing the meaning of `large-house-v1`.
+
+The `cleanFloor` entry ceiling is 160: the reviewed fixture currently warms
+120 deterministic room/physical-body entries, and the extra 40 slots allow a
+legitimate fixture extension without weakening the separate zero-growth gate.
+
+The absolute switch-cycle/Long-Task ceilings include roughly 20–30% headroom
+over the paired 2026-08-09 Ubuntu run where the unchanged base and candidate
+both reached about 5.3 s / 2.45 s / 22 tasks / 9.9 s total under runner load.
+The same-runner relative checks remain tighter for an actual candidate-only
+regression; this prevents an overloaded but symmetric runner from turning an
+absolute safety ceiling into a flaky code-regression signal.
